Notes. K denotes the semi-amplitude of the RV sinusoid at the given harmonic of the stellar orbital period, A the semi-amplitude of the photometric sinusoids, φ the phases of the sinusoids (in common between RV and photometry). Only one parameter has been used for the jitter term in the B light curves, obtained during 2014 and 2015. All the parameters have been fitted except:
